Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal display substrate with which the easy execution of the remedy to hillocks is possible even if aluminum or its alloy is used as conductive layers by coating the surface of at least the parts of the first conductive layer to be superposed on another conductive layer with an ITO film. SOLUTION: At least the parts of the upper layer to be superposed on the other conductive layer are previously coated with the ITO film in the case where the aluminum or its alloy is formed as the ITO film of the lower layer. Scanning signal lines 2 formed first on the main surface of the transparent substrate 1 are composed of an alloy of, for example, Al-Ti-Ta and both flanks parallel with its extension direction are formed gently to a tapered shape. Hillock preventive films 5 are formed atop the scanning signal lines 2 in the state of completely covering both flanks of the scanning signal lines 2. The hillock preventive films 5 are composed of the ITO films. Pixel electrodes 4 are formed of the ITO films and are formed by the same stage as for the hillock preventive films 5. As a result, there is no need for adding a special stage to the formation of the hillock preventive films 5.

Abstract: PURPOSE:To enable simultaneous image pickup of celestial bodies being different in brightness in a large degree and also highly precise measurement of positions, by dividing the brightness on a CCD image-sensing plane and also by integrating a charge of CCD while transferring it in coordination with a spin motion. CONSTITUTION:Lights from celestial bodies, a planet, a satellite thereof and a fixed star, which pass through an optical system 1 form images from the celestial bodies on an image-sensing plane of two-dimensional CCD 2 disposed on a focal plane of the optical system 1. In relation to a shift in the horizontal direction due to a spin motion of a probe, a CCD drive circuit 3 integrates charges on the CCD 2 while transferring them sequentially to adjacent pixels in accordance with a speed of the shift, whereby a blur of the image is reduced. A subject-catching area of the CCD 2 driven by the circuit 3 is divided in accordance with brightness of the same image-sensing plane, an exposure time therefor is made short or long and thereby images of the celestial bodies being different extremely in the brightness can be acquired simultaneously. A detected image signal of the CCD 2 is processed by a CCD image signal processing circuit 4. In this way, the images of the celestial bodies being different in a brightness difference are picked up distinctly on the same screen and thereby reduction of an error can be attained.
